Volkswagen has offered the public a first glimpse of its future mobile quick charging station.

The mobile charging station works according to the principle of a power bank – which is familiar to many people with smartphones – but for electric vehicles instead.

The charging point can be set up flexibly and independent of the power supply wherever it is needed: for example, in public parking lots in the city, on company premises, or as a temporary charging point at large-scale events.

The charging capacity of up to 360 kWh enables up to 15 e-vehicles, including members of Volkswagen’s new ID. family,1 to be charged in stand-alone operation. Thanks to quick charging technology, the charging process2 only takes 17 minutes on average. If the energy content of the integrated battery set is less than 20%, the depleted charging station is simply exchanged for a charged one. If, however, it is permanently attached to the power supply with up to 30 kW via alternating current, the battery pack perpetually recharges itself. In case the charging process is based on renewable Power bank for electric cars – the mobile quick charging station by Volkswagen Group Components power supply, the charging station furthermore allows the temporary storage of sustainably generated power, such as solar or wind energy – and therefore CO2-neutral mobility.

The first mobile quick charging stations will be set up as early as the first half of 2019 in Volkswagen’s hometown of Wolfsburg, Germany as part of a pilot project, and will support the expansion of a charging infrastructure in the urban area. As of 2020, the charging station will also be implemented in other cities and communities.

Thomas Schmall, Chairman of the Board of Management of Volkswagen Group Components, said: “The mobile charging stations are a decisive step toward an efficient network of charging points. They can be set up anywhere as required – with or without connection to the power supply. This flexibility enables a completely new approach for the rapid expansion of the charging infrastructure. Cities can, for example, find out the most suitable places for a permanent charging point before making major investments in developing the network. In addition, it will be possible to set up a large number of charging stations temporarily – exactly when and where they are needed.”

The mobile charging stations can be set up at defined points, for example, spread out across a city. The flexible locations can be easily found via the Internet or apps. Each charging station enables DC quick charging with up to 100 kW. In addition to electric cars, e-bikes can also be charged. Up to four vehicles can be charged simultaneously: two with DC and two with AC connections. The total battery storage capacity of up to 360 kWh is sufficient for up to 15 e- vehicles. There is also the possibility of connecting to the power supply directly, allowing the station to be charged with up to 30 kW via alternating current by means of a permanent standard grid connection. This enables charging points for electric vehicles to be set up quickly and simply, without any structural changes or major financial outlay. The battery pack in the charging station can be recharged around the clock thanks to the direct power connection. This time-independent recharging, and therefore buffering of power, also considerably reduces the strain on the power supply at peak periods.

Mark Möller, Head of Technical Development at Volkswagen Group Components said: “Our mobile charging stations offer a further crucial advantage. It is only when an electric car is charged with sustainably generated power that it can claim CO2-neutral mobility. Our charging station is the first to offer the possibility of temporarily storing sustainably generated power.” For example, the charging station can be charged specifically with solar or wind energy, which is then transmitted to the electric vehicles during charging. Technically, the mobile charging column is based on the battery pack of the Volkswagen Group’s Modular Electric Toolkit (MEB). On the one hand, this offers the advantage of quick scalability and, on the other hand, the charging station allows batteries from electric vehicles to have a second life. This is because a battery loses charging capacity over time. If a vehicle battery has a defined, reduced residual capacity, it is exchanged. If this battery subsequently passes a thorough analysis, it can be reused in a mobile charging station.

An efficient network of charging points is regarded as one of the basic infrastructural prerequisites for convincing customers to buy electric vehicles such as the Volkswagen brand’s future I.D. family.1 Accomplishing this is one of the major challenges Volkswagen Group Components and others must tackle to ensure the breakthrough of e-mobility. As of January 1, 2019, the Components division is an independent business unit within the Volkswagen Group. The mobile charging station is an in-house development with the goal of developing a closed life cycle for the battery. The start of production is planned for 2020.

AES Corp seals 10-year carbon-free energy deal with Google

AES Corporation will ensure energy powering Google's Virginia data centers will be '90% carbon free'

The AES Corporation has struck a 10-year supply contract with Google to provide near-carbon-free energy to power its Virginia-based data centers which will start later this year.

Claiming the first clean energy procurement deal in the world of its kind, AES will help ensure that the energy powering those data centers will be 90% carbon-free when measured on an hourly basis.

AES will become the sole supplier of the data centers' carbon-free energy needs on an annual basis, sourcing energy from a portfolio of wind, solar, hydro and battery storage resources to be developed or contracted by AES.

The agreement marks an important step in meeting Google's previously announced goal to run its business on 100% carbon-free energy on an hourly basis by 2030.

"Last year, Google set an ambitious sustainability goal of committing to 100% 24/7 carbon-free energy by 2030. Today, we are proud that through our collaboration with Google, we are making 24/7 carbon-free energy a reality for their data centers in Virginia," said Andrés Gluski, AES President and CEO. "This first-of-its-kind solution, which we co-created with Google, will set a new sustainability standard for companies and organizations seeking to eliminate carbon from their energy supply."

"Not only is this partnership with AES an important step towards achieving Google's 24/7 carbon-free energy goal, it also lays a blueprint for other companies looking to decarbonize their own operations," says Michael Terrell, Director of Energy at Google. "Our hope is that this model can be replicated to accelerate the clean energy transition, both for companies and, eventually, for power grids." 

AES assembled the 500MW portfolio from a combination of AES' own renewable energy projects and those of third-party developers, which were selected, sized and contracted to meet Google's energy needs across a number of considerations, including cost efficiency, additionality and carbon-free energy profile.

The portfolio assembled by AES is expected to require approximately $600 million of investment and generate 1,200 jobs, both permanent and construction, in the host communities. These efforts will greatly simplify Google's energy procurement and management at a competitive price while decarbonizing Google's load and the broader PJM grid.

This supply agreement follows on the strategic alliance AES and Google formed in November 2019 to leverage Google Cloud technology to accelerate innovation in energy distribution and management and advance the adoption of clean energy. AES is pioneering greener, smarter energy innovations, with the goal of expanding the services available to large-scale corporate customers.

The Google.org Impact Challenge on Climate commits €10M to fund bold ideas that aim to use technology to accelerate Europe’s progress toward a greener, more resilient future. Selected organisations may receive up to €2M in funding and possible customised post-grant support from the Google for Startups Accelerator to help bring their ideas to life.

Last year it issued $5.75 billion in sustainability bonds to fund ongoing and new environmentally or socially responsible projects. To read its 2020 Environment report, click here.
